GLASS-CUTTING BOARD.

Specification of Letters Patent.

Patented J an. 30, 1906.

Application filed July 25, 1905. Serial No. 271,237.

' To all whom it may concern:

Be it known that I, EDWARD W.O1-IAD- WIOK, a citizen of the UnitedStates, residing at Edgartown, county of Dukes, and State ofMassachusetts, have invented an Improvement in Glass-Cutting Boards, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like numerals on the drawings representinglike parts.

This invention relates to a novel device for use in cutting glass; andit comprises a board on which the glass rests and which is providedadjacent its edges with graduations representing units of measure.

One edge of the board. is provided with a flange rising therefrom whichconstitutes a gage against which the glass may rest while being cut.

Cooperating with the board is a straightedge for guiding the glasscutter. Said straight-edge rests at one end upon the gage and is thussustained at said end slightly above the .glass on the board and is heldin its adjusted position on the board by two clamping members, whichengage the edges of the board.

In using the improved device the glass is placed on the board with oneside resting against the gage and the straight-edge applied to theboard, as above described, and adjusted thereon to bring the edgethereof along the line where it is desired to cut the glass. Saidstraight-edge is then clamped in position, and the glass may be cut tothe desired size by moving the glass-cutter along the edge of thestraightedge.

The particular features wherein my invention resides will be referred toin detail in the accompanying specification and pointed out in thefollowing claims.

Figure 1 is a plan view of a board embodying my invention. Fig. 2 is anedge view thereof. Fig. 3 is a section, on an enlarged scale, on theline 00 it, Fig. 1. Fig. 4L is a section, on an-enlarged scale, on theline 1 7 Fig. 1. Fig. 5 is a section on the line 2 2, Fig. 4; and Fig. 6is a section on the line b I), Fig. 1.

The board is designated by 3 and. is preferably made rectangular, thoughit might have any shape without altering the invention. The surface ofthe board on which the glass rests is preferably ruled or provided withparallel lines 1, which are conveniently spaced at a distance of an inchapart. In the board illustrated in Fig. 1 these lines are arranged atright angles to each other and parallel with the edges of the board.

One edge 5 of the board is provided with a flange 6, which rises fromthe board and which constitutes a gage against which one edge of theglass 7 to be out may be placed, said gage having a thickness slightlygreater than the glass to be cut.

16 designates a straight-edge, which is of a length to extend clearacross the board. On one end of the st eight-edge is adjustably mounteda clamping member 11, which is provided with a clamping-foot 12 to restagainst the edge 8 of the board and a shoulder 9 to rest on top of theboard, said shoulder operating to space the straight-edge from the boardsufficiently to prevent the straight-edge from resting on the glass.

The clamping member herein illustrated. is provided with an aperturethrough which the straight-edge extends and is clamped to saidstraight-edge by any suitable means, such as a cl an'iping-screw 13.

The opposite end of the straight-edge is provided with a clamping member14, which has adjustably mounted therein a foot 15, adapted to restagainst the edge 5 of the board, said foot having a rounded edge 16 forthe purpose hereinafter described. This foot 15 has swiveled thereto aclamping screw 17, in screw-threaded engagement with the clamping member14, whereby the foot may be adjusted relative to the clamping member.Said clamping member is provided with suitable guides 18, by means ofwhich the foot is guided in its movement.

I prefer to make the clamping member 14 rigid with the straight-edge 10,although it could. be adjustably secured thereto, if desired. Theclamping member 11, however, is adjustably mounted on the straight-edgefor reasons which will hereinafter appear.

When the straight-edge is in. place on the board, one end thereof restson and is supported by the gage 6, while the other end is heldsu'lliciently above the board to accommodate the glass by the shoulder 9on the clamping member 11, as shown. The top surface of the gage 6 isruled or provided with graduations, and. the surface of the boardadjacent the edge 8 is also provided with similar graduations. Forconvenience I prefer to make these rules in inches. The edge 20 of theboard may also be provided with a gage 21, similar to the gage 6, andthe top surface of the gage 21 is also ruled in inches and the surfaceof the board adjacent the edge 22 similarly ruled.

In using my improved board the glass 7 to be cut is placed With itsedges against either or both of the gages 6 and 20, as illustrated, andif it is desired to out said glass twenty by twenty-four inches, forinstance, the straightedge is adjusted until one edge thereof coincideswith the 20 mark on the scale at opposite sides of the board, and thenit is clamped in such position by tightening up the adjusting-screw 17and clamping the foot against the edge of the board. Theoperator thenmoves the glass-cutter in contact with the straight-edge over the glass,thereby cutting it to the desired dimension. For get ting the otherdimension the glass may be shifted on the board, or the straight-edgemay be removed and made to extend between the edges 20 and 22 or atright angles to the position shown in Fig. 1, and after .having beenproperly clamped in adjusted position the other dimension of the glassmay be secured.

Since the board illustrated is longer in one dimension than in theother, I have made the clamping member 11 capable of adjustment on thestraight-edge.

To prevent the straight-edge from becoming wornby the clamping-screw 13I prefer to embed therein at appropriate points wearing-washers 25.

The reason for making the surface 16 of the foot of the clamping member14 rounded is to permit the straight-edge to be swung into an angularposition, as shown in dotted lines, Fig. 1, and to be firmly clampedtherein when it is desired to cut one edge of the glass on an angle.

Various changes may be made in the construction of the device withoutdeparting from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Let ters Patent, is

l. A board for cutting glass having on one side a gage which projectsabove the surface of the board, a straight-edge of a length to extendacross the board, one end of said straight-edge being adapted to rest onthe gage, means carried by the straight-edge to space the other endthereof from the board,

and means to clamp said straight-edge to the board in any adjustedposition.

2. A board for cutting glass having on two adjacent sides a gageextending above the surface of the board, and against which the glass tobe cut rests, a straight-edge resting at one end upon said gage, twoclamping members on said straight-edge to clamp it to opposite edges ofthe board, one of the clamping members being constructed to space theadjacent end of the straight-edge above the board.

3. A board for cutting glass having a scale on the surface of the boardadjacent one edge, a gage applied to the opposite edge of said board andextending above the surface of the same, the surface of the gage havinga scale applied thereto, a straight-edge resting at one end upon saidgage, a clamping member secured to said end of the straight-edge, saidclamping member having an adjustable foot to engage the adjacent edge ofthe board, and anotherclamping member secured'to the opposite end of thegage and having a foot to engage the adjacent edge of the board, saidlatter clamping member having a shoulder to rest on the top of the boardand thereby space from the board the end of the straight edge to whichit is secured.

4. A board for cutting glass having a scale on the surface of the boardadjacent one edge, a gage applied to the opposite edge of said board andextending above the surface of the same, the surface of the gage havinga scale applied thereto, a straight-edge resting at one end upon saidgage, a clamping member secured to said end of the straight-edge, saidclamping member having an adjustable foot to engage the adjacent edge ofthe board, and another clamping member adjustably secured to theopposite end of the gage and having a foot to engage the adjacent edgeof the board, one of said feet having a rounding edge.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDWARD N. OHADWIOK.
